MEP-802A Are they worth having?

[TxBlacksmith]

I have been thinking of buying a MEP-802A to use at my cabin.  Basic needs are for lights, fridge, and a window unit during the hot times.  During hunting season, it might get run for 4-6 days.  My cabin is nowhere close to the grid...thanks to a jerk-ass neighbor who wont grant me a right of way.  Seems these things cost about  $2500.00 and up.  Built to mil-spec, I would think these to be solid units?
Opinions?
